1 Corinthians 7:38 - Matthew Poole's English Annotations on the Holy Bible

So then he that giveth her in marriage doeth well: there is no general rule for all parents in this case, where the duty or sin of parents may arise from their or their children's different circumstances. But supposing that a parent, having duly weighed all circumstances, be fully resolved, and he finds the child's will concurring, that she can forbear, and is willing to do in the case what her parent desires; in such a case as this, if the parent disposeth her in marriage, I cannot say he sinneth, but he doth what he may do. But he that giveth her not in marriage doeth better; but with reference to the present state of things in the church and in the world, and with reference to the young woman's liberty for the service of God, he doth better, if he doth not so dispose her. The thing is in itself indifferent, and Christians must be in it ruled and inclined one way or another from circumstances.
